Description
The recent advent of hardware architectures characterized by many-core or
accelerated processors has opened up new opportunities for parallel programming
models using SIMD or SIMT. To meet ever increasing needs of computing
performance for future HEP experimental programs, the GeantV project was
initiated in 2012 to exploit both the vector capability of mainstream CPUs and
multi-threading capabilities of coprocessors including NVidia GPUs and Intel
Xeon Phi. Major objectives of GeantV cover all levels of parallelism managed
by a concurrent task scheduler for processing multiple particles in highly
parallel manner with vectorized geometries and physics algorithms. In this
paper we describe implementation of portable physics models of electromagnetic
processes that can be commonly used in hybrid computing platforms. Preliminary
performance evaluation and validation results of new vector physics models on
both CPU and coprocessors will be presented as well.
